Hey guys, I just recently changed my fuel filter, got a K&N drop in, removed the silencer, and put in a Synthetic Blend (soon going to full synthetic) I've recieved a noticable drop in gas mileage.
I put in fuel system cleaner and no difference. Can anybody help me out on this one??

Drive slower.

Maybe it's time for a tune-up. Everything you've done would help gas mileage rather than hurt it.

New plugs, i run copper autolite 764's I belive, there alwase out of the NGK's. just use your compressor and blow off the top of the intake before removing the rails and after removing the COP's and before removing the old plugs.

I don't think it's time for a tune up, she only has 46K on her. So I guess, little stabs at the throttle guzzles that much? Hmmm...

Hell my old probe gt can be floored all day long and maybe take a 1/4 tank and still run 13s.

(thinking to self) can not pull hoes with a car named after what the hoes use

Good point! heh heh
